    2013 Jeep Graqnd Cherokee

    My 2013 JGC hs the 5.7 HEMI and 65RFE transmission. It's been dyno tuned with HPTuners.
    I just installed the Revmax upgraded HD valve body, and I am looking to set my line pressures to an optimal setting with this new valve body in. I have posted what is in my current tune and was hoping for some guidance on what to bump these numbers, if any, up to, before starting the quick learn procedure. Also, should I enable 2-3 shift?

    It’s all personal preference

    That is not helpful at all.
    Could we start with what these mean? For instance, the "max line pressure" has 21 datapoints. The numbers recorded there also vary, and not in a way that makes sense. Line pressure gain per gear? What does that mean and why are they different?
    And what is the "duty cycle" between gears, and why is there 8 different number for each "gear change"?

    Well you didn’t ask what any of it means, you asked what to put in them and it’s all personal preference. The line pressure that has 21 different data points are the different shifts that can occur, somewhere in one of the threads it tells you what each one is. Gain is just how aggressive it goes to max pressure as torque demand increases and the duty cycle, well, its duty cycle of the shift solenoids based on torque for that particular shift hence why you see 8 different data points in it.

    I've searched and I can't find this information. I've read thread after thread after thread.

    I did obtain a "stock file" so I could compare my current one, and I am noticing that there isn't much difference between the the two. Therefore, I am hoping someone will actually help me understand all these tables and what I can do to make the shifts firmer, make the tranny last, and give the best street performance, all while taking advantage of the upgraded valve body.
